The Magnum MPSC403WEAXX2F features a three-pole, drawout vertical mounting configuration within a double standard frame for flexible installation across panel sizes, delivering robust fault control in dense electrical rooms. The 100 kA short-circuit rating translates to improved protection for feeders and motors, reducing arc energy exposure and downstream damage. The 4000 A current rating supports high-load applications and future expansion without replacing the breaker, lowering total cost of ownership. The PXR20 LSIGAM trip unit provides enhanced protection, faster fault clearance, and traceable event data for maintenance planning. Compatibility with Power Xpert Protection Manager enables centralized protection coordination, alarm management, and remote diagnostics, improving uptime and asset lifecycle. Zone selective interlocking resources further optimize coordination, minimizing nuisance trips and improving system reliability. Proven certifications from ANSI, UL, and multiple global bodies reinforce compliance across regions, easing procurement and insurability for end users. System integration with motor protection strategies and selective coordination supports lower operating costs and safer, more predictable plant performance.
